Screws
 

I used screws for my wingtips. I purchased the the click bond kit:

It worked really well...

Wing Tip Hinge
 

Mine is an RV-14, but the RV-10 wingtip is identical. I used the website provided by Mike in Post #2, thanks Mike!
I just pushed the rib a bit deeper to allow space for the piano hinge. Added a nut plate and built the end piece shown from some left over materials.

I also did this on a 14. However, rather than swapping sides, I moved the rib outboard 5/16?. This left room for a 1/4? thick delrin block to capture the hinge pins like shown above (held by screws/nut plates). I considered swapping, but decided I like the aesthetics of no flanges.

Thanks all.
Plenty of good suggestions there.
Hinges were never in doubt for me.
My -7 has them and it?s far superior to screws IMHO.
Aesthetically better, more practical (less than 60sec to remove them),
and more likely to stand the test of time. Must have had my tips off 10times over 8y for various reasons. No paint damage at all.
I?m surprised it?s not the factory default. The only downside is probably the weight penalty.
